ALCOHOL-HEATER.

SPECIFICATION forming part of Letters Patent No. 731,069, dated June 16,1903.

Application filed September 3, 1902'. Serial No. 122.013. (No model.)

T0 @ZZ whom, t may concern,.-

Be it known that I, EUGENE R. PLUMMER, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements inAlcohol-Heaters, of which the following is a specification.

My invention relates to portable heating devices used to quickly heat asmall amount of water or other liquid with alcohol or other likecombustible fluid; and the objects thereof are to provide a heater ofsimple construction with few-parts that can be readily put intooperation, that will heat the contents rapidly and with very littleexpense, and which can be packed compactly for transportation. Iaccomplish these objects by means of the device illustrated in theaccompanying drawings, in Which- Figure 1 shows my improved heater, theleft one-half in elevation and right one-half in vertical section, thelamp being shown in dotted lines in the boiler in the position it is inwhen the heater is packed ready for transportation. Fig. 2 is a planView of the lamp. Fig. 3 is a plan view of the boiler, the cover andhandle being in their open position and partly broken away.

In the drawings, A is the alcohol or other liquid holding lamp providedwith a central draft-tube B, the upper portion of which is perforatedand extends above the liquid-reservoir D, which is filled with somenon-combustible porous material'E, asbestos being preferred, which isheld in the receptacle by a wire screen F. The liquid-reservoir isprovided with hinged covers G to cover the liquid when the lamp is notburning. The covers may be turned so as to entirely cover or uncover thetop of the reservoir. The inner edge of the cover fits into an annulargroove H to make a tight joint. The outer casing of the reservoirextends below the bottom of the liquid-holding space thereof and forms aprojecting flange or base I for the lamp, which is provided with aplurality of portsJfor the passage of the air into the draft-tube. Theseports are controlled by al damper K, having ports K', which registerwith'the ports of the base when the damper is open. This damper isprovided with a handle or knob L,

lamp is removed from the boiler.

which projects through the ports in the base and keeps the damper fromseparating from the base, by means of which the damper is operated toopen or close the ports of the base Io regulate the amount of airadmitted to the draft-tube.

The lamp is provided with handles M, preferably of wire, hinged thereto,which are of such shape that they may be turned to lie close against thesides of the reservoir when desired, the closed position being shown indotted lines in Fig. 1.

The boiler N, which is designed to hold the liquid to be heated, has abase N', which is adapted tofit into the top of the draft-tube and to beheld thereby in an upright position, as shown in Fig. l. It is providedWith a hinged handle O, which may be closed inte the boiler, as shown indotted lines in Fig. l.

The boiler also has a hinged lid P and a The boiler above the base,which is prefer-Y I ably circular, is preferably in shape a truncatedcone, and the lamp is preferably of a similar shape,.except the.draft-tube, whichl is preferably'circular. Other shapes may be usedwithout departing from the spirit of my invention, which is embodied ina boiler Whose sides are outwardly toward the top, adapted to be heldcentrally by a lamp having an opening surrounding the bottom of theboiler, so that-the flame will impinge the sides of the boiler.

The central draft-tube may be omitted, if desired, suitable provisionsbeing made to hold the boiler; but I prefer its use, as it providesbetter combustion for the fuel.

I have shown in dotted lines in Fig. 1 the lamp placed in the boiler,which is the position it occupies when it is desired to transport theheater to any considerable distance, as when traveling.

l/Vhen it is desired to use the heater, the

The reservoir is filled with liquid fuel, and the boiler, with theliquid to` be heated in it, is placed on the lamp, which is thenlighted. The flame instantly surrounds the sides of the boiler, and asit is in shape a truncated cone it presents a -large surface to theflame, thereby IOO enabling the heating of its contents much quickerthan if applied to the bottom, as is usual with alcohol-heaters.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is*- 1. A heater comprising a main liquid-holdingvessel; in shape an inverted truncated cone; a base to support saidvessel the said base adapted to hold liquid fuel and when not in use todrop into the main vessel; a handle pivoted to the top of said vesseland adapted to be thrown over and into the Vessel so that the top can beclosed while the base and liandle are inside the vessel; a lid pivotedto said vessel, as shown. f

2. The herein -deseribed alcoholheater, comprising thetruncated-cone-shapedboiler; the alcohol-lamp, of such a shape to iii;into the boiler; a liquid fuel reservoir in said lamp; a draft-tubecentrally disposed within said reservoir, the top of which extends abovethe reservoir, said tube above the reservoir,
